Product Overview
Caterpillar lists 2W1223 as a coolant water pump for 3204 engines and multiple machines powered by that engine. It should not be broadly labeled as a 3208 pump without verifying the exact pump because Cat uses different water-pump families on 3208 applications.
Key Features & Performance
- Cat reference 2W-1223
- Factory-fit 3204 engine water pump
- Used across loaders, dozers, skidder and industrial 3204 applications

Common Reasons for Replacement
- Coolant leaking from pump seal

Frequently Asked Questions
How do I confirm fitment? Confirm 2W-1223 or a valid superseded/cross-reference number in the Cat parts catalog. Do not assume 3208 fitment from the old title alone.
Is this an OEM part? This listing is for a replacement part. Brand names and OE/reference numbers are used to identify fitment unless the listing specifically states that the item is genuine OEM.
